The prior art.

Implementation of a technical solution.

The receiving separator of the installation of a comprehensive gas installation (Fig. 1, Fig. 2) consists of two main parts: a cork trap (1) and a vortex-type filter separator (7). The cork trap (1) is a horizontal cylindrical container (2) having an inlet pipe (3), a gas outlet pipe (5) and a drain pipe (4). A device for collecting and removing mechanical impurities (6) is mounted inside a horizontal cylindrical tank (2). The vortex-type filter separator (7) contains a vertical cylindrical body (8) in which a gas inlet pipe (11) is mounted, an upper bottom (9) containing an outlet pipe (12) and a lower bottom (10), with a drainage outlet ( 13). Inside the vertical cylindrical body (8), a deflector (14) with a reflective plate (15), a separation bag (17) and a false bottom (20) are placed. The inner surface of the vertical cylindrical body (8) of the vortex-type filter separator (7), the deflector (14) and the reflective plate (15) form a catch pocket (16) designed to divert fluid from the vortex stream, pressed by centrifugal force to the inner wall of the vertical cylindrical housing (8), and transporting it to the drainage outlet (13). The separation package (17) is cylindrical in shape and contains flat curved separation plates (18) located in its forming surface and forming identical and constant size slotted channels (19) in the overlap zone. The vortex-type filter separator (7) is mounted on top of the cork trap (1). The gas inlet pipe (11) is connected to the gas outlet pipe (5) of the sample catcher (1) by a connecting pipe (21). The drain outlet (13) of the lower bottom (10) of the vortex type filter separator (7) is connected to the drain pipe (22), the lower end of which is located in the lower part of the horizontal cylindrical container (2) of the sample catcher (1).

The receiving separator installation complex gas treatment works as follows.

The gas-liquid mixture through the inlet pipe (3) enters the cork trap (1), designed for preliminary gas purification, protection of separation equipment from volley liquid inflows and gas separation from mechanical impurities and liquid. In the cork trap (1), the direction of movement of the gas-liquid mixture changes and its speed decreases. Due to shock separation, gravitational forces and coagulation of droplets, mechanical impurities and liquid are deposited at the bottom of the horizontal cylindrical tank (2) of the cork trap (1). The mechanical impurities accumulated at the bottom of the horizontal cylindrical container (2) of the cork catcher (1) are collected and removed from the container by a device specially mounted in it for collecting and removing mechanical impurities (6). Next, the pre-purified gas, changing direction and speed, is fed through the connecting pipe (5) through the connecting pipe (21) to the inlet of the vortex-type filter separator (7). With a change in the direction and speed of the gas, additional liquid is released from the gas and deposited at the bottom of the horizontal cylindrical tank (2) of the cork trap (1). The liquid accumulated at the bottom of the horizontal cylindrical tank (2) is discharged through the drain pipe (4).

The gas to be subsequently cleaned enters the vortex type filter separator (7) through the gas inlet pipe (11). The deflector (14) smoothly changes the direction of gas movement and forms a vortex gas movement around the separation package (17). In the space formed by the inner surface of the wall of the vertical cylindrical body (8) of the vortex type filter separator (7) and the separation bag (17), the bulk of the liquid is released from the gas stream. Drops of liquid are discarded by centrifugal force on the inner surface of the wall of the vertical cylindrical body (8) and under the influence of inertial and gravitational forces move along this wall in a downward spiral in the direction of rotation of the gas stream. At the same time, part of the liquid enters the trap pocket (16) and flows down its walls to the false bottom (20). Having reached the plane of the false bottom (20), the liquid passes through the annular gap between the inner surface of the vertical cylindrical body (8) and the false bottom (20) and is transported to the drainage outlet (13) made in the lower bottom (10).

A finely dispersed droplet liquid that has not settled on the inner wall of the vertical cylindrical body (8) enters the outer surface of the separation plates (18) and is transported by gas flow through the slotted channels (19) to their inner surface. Descending along the inner surface of the separation plates (18), fluid particles flow onto the surface of the false bottom (20), from where they enter the lower bottom (10) through the annular gap between the inner surface of the vertical cylindrical body (8) and the false bottom (20). The liquid accumulated in the lower bottom (10) through the drainage outlet (13) through the drainage pipe (22) is discharged into the lower part of the horizontal cylindrical tank (2) of the sample catcher (1).

The cleaned gas stream is directed to the outlet pipe (12).

Industrial applicability.

The claimed technical solution is implemented using industrially produced devices and materials, can be manufactured at any machine-building enterprise and will be widely used in the oil, gas and other industries.
